We prove that for every programmed grammar, there exists an equivalent programmed grammar where only a single rule has more than one successor.\u00A0 Furthermore, we establish an infinite hierarchy of language families resulting from the cardinality of successor sets. Open problem areas are formulated in the conclusion of the paper."@en . "[917D590B27CA]" . "3"^^ . . "26230" . "Formal languages, Programmed grammars, Nondeterminism, Generative power"@en . "3"^^ .
